i don’t know input params is invalid,it’s return 8 (NV_ENC_ERR_INVALID_PARAM)

can you help me? thanks!

Internally tracking this issue under Bug 200034505 : NVENC H.264 encoder initialization failed with GTX 750Ti / gtx 750 (GM107) / GTX650TI

Extracted nvenc_4.0.0_linux_sdk.zip and found its mentioned inside doc folder in NVENC_DA-06209-001_v04.pdf Page-7 Table-3
“The current SDK package allows 2 NVENC sessions for Low end Quadro and Geforce cards on Windows OS only.”

And in README inside \Samples\nvEncodeApp
"NVENC is officially supported on GPU hardware based on Quadro, Tesla, GeForce GRID, or VGX.

““NVENC on GeForce is not officially supported.””

Hi, sandipt, you mean that GTX 750Ti is not support nvenc with nvenc_4.0.0_linux_sdk.zip on Ubuntu os?

how can I find the Bug 200034505 info?

and when will the Bug 200034505 be solved?

Thank you very much!

Yes! GTX 750Ti is not support nvenc with nvenc_4.0.0_linux_sdk.zip on Linux. This is internal bug.

Hi, I use GTX 750Ti in win8, and get error as belows:

nvEncoder.exe -configFile=HeavyHand_1080p.txt -outfile=HeavyHandIdiot.3sec.264

Hi, sandipt, I have the same error on nVidia Quadro K2100M (GK106).

P.S. On Quadro K4000 (GK106) the NVENC works good.
nvidia-bug-report.log.gz (183 KB)

correct me if i’m wrong but i thought 346.16 was required to enable the use the NVENC encoder on the supported GPU’s. I’ve enabled NVENC encoding by using the ffmpeg_libnvenc fork on github.

Well you are kind of right, nvenc was first supported in linux only by couple of quadros and explicit license file were needed. Some driver version cut the need of license file and broadens support to geforce cards, I don’t know though did them really worked before 346.16 driver … but there has problems with newer quadros and geforces before that beta driver. And the error

nvEncoder Error: NVENC H.264 encoder initialization failure! Check input params!

was the error for revealing driver bug that prevent nvenc working. Only way to get it working now, is to use newest beta driver.

so if you’re running 346.16 driver from nvidia, you should be able to get nvenc working is what i’m saying. I’m in the process of trying out the ffmpeg_libnvenc but i’m having issues in Arch.

Thanks a lot, with 346.16 driver NVENC works on Quadro K2100M!

HI

I got this error can you suggest me how to fix it…
